The premise of the show is: Everybody lies. Kutner has been depicted as someone who seem happy and well adjusted despite the traumatic death of his parents. He’s also depicted as a masochist, trying out new things for the thrill of it.

In S5 Ep 20, Kutner killed himself for no apparent reason or is there a reason? My hypothesis is, Kutner lied: about being over the trauma of his parents’ death, of being well-adjusted, of fitting in. In reality, everything was all at face value. The suicide is an act of saying: “I got tired of lying. I got tired of being miserable.” Its been a recurring thought in the show that House is miserable but he’s able to keep his misery at bay through his vicodin addiction, his obsession on solving puzzles and getting answers. These are all his way of dealing with his misery. Perhaps, Kutner’s way is exploring new things, appearing as if he didn’t care. And one day he just got up and got tired of living the lie…I’ve watch the ep dozens of times and the title hit me: SIMPLE EXPLANATION. The simplest explanation for his suicide is, he lied. Everybody lies….hats off to the writers of House…so far the best ep after Wilson’s Heart.
